Programmable Relay: ZEN's Minimum Product Configuration

ZEN Programmable Relays: What is the minimum product configuration needed to use the ZEN Programmable Relay?

Answer

Basically, you can use ZEN with only a CPU Unit. With the LCD-type or Economy CPU Units, programming and parameter settings can be performed using the LCD and buttons on the front panel.Because there are no display and buttons on the front of the LED-type CPU Unit (ZEN-[]C2), you need ZEN Support Software and a personal computer connection cable for programming, or you can copy the program from another CPU Unit with a Memory Cassette (ZEN-ME01).
